David Keats, Founder and Managing DirectorI have worked exclusively in the welding industry since the mid 1970’s,and have gained extensive experience, within the following industry sectors;

Pressure vesselsProcess pipe workHydraulicsChemical/storage tanksRailwaysGlass mould industryAircraftStructural steel and bridgesLifting & HGV Trailer equipmentMarineOffshore & inshore commercial divingUnderwater wet and dry hyperbaric welding

I have also attained qualifications in non-destructive testing (NDT),including; ultrasonic, magnetic particle, dye penetrant and weldinginspection. I Qualified as a commercial air diver in 1983 and worked inthe offshore and civil engineering sectors, as both a wet and dry hyperbaricwelder. In 1987 I set up Hydromech Technical Services Ltd (HTS) andqualified as a welding instructor through the STA College in 1989, as wellgaining a range of other technical (TWI) welding qualifications. In 1990and I wrote my first book, The Professional Divers Manual on Wet Welding,which was published by Woodhead Publishing (part of the TWI ). In 1991,in association with The Marine & Engineering Training Association (nowEAL), I ran the UK’s first National Qualification in underwater welding andbegan offering training courses in the UK and overseas. By 1994 we hadbecome the UK’s only approved test and assessment centre. Continuingwith my studies, I qualified as an International/European weldingtechnologist and received a Diploma in welding engineering andtechnology from TWI in 1992 and 1997 I gained my National Certificatein metals technology from Bradford & Ilkley College. I then qualified as aSenior Welding Inspector at TWI in 2000. I established Speciality WeldsLtd in 2002, following an MBO from the MOS International Plc Group,where had been responsible to the board for all welding, training,

inspection and product manufacturing. In 2004 I completed the secondrevised edition of my book, A Welder’s Mate, published by Troubadour.In 2010 and I was accepted as a Member of BINDT and I am currentlyworking towards CEng status. My ethos is to offer a comprehensiverange of professional services to the welding industries, including; weldertraining and qualifications, NDT/weld testing, consultancy and technicalservices and a wide range of other related welding products and services.

I have committed my life to welding and in turn, it has given me a lifetimeof experiences and skills that I hope will be of service to you.

Underwater Welder Training

As accepted World leaders in the provision of underwater welder training,Speciality Welds is proud to offer a world’s first. The only independentlyquality assured, accredited and audited programme of this kind; TheWeldcraft- Pro™.

This course is fully certified by EAL, part of SEMTA - Sector Skills Councilfor Science, Engineering and Manufacturing Technologies, the UK’sleading awarding body for engineering qualifications. The course is alsorecognised by IMarEST - The Institute of Marine Engineering, Science andTechnology. The Weldcraft-Pro™ is delivered, under license, throughapproved diver training schools. The training is based on an 80 hourprogramme, split over two phases, covering both dry and wet welding andis open to both non-welders and welders alike. All training follows theInternational Institute of Welding (IIW) and European Welding Federation(EWF) syllabus 570-01 for fillet welder – plate and covers the followingtopics;

Training is designed to provide commercial divers with the competenciesin both theory and practice of underwater manual metal arc (MMA) welding.Welder approval qualifications are conducted in accordance with thefollowing welding standards; BSEN ISO 15618-1, AWS D3.6-2011 andcan also include BS4872-1

Underwater Welding & Cutting Products

The Barracuda Gold is a specially formulated flux coated MMA weldingelectrode, which has added nickel for improved strength and toughness.It has a specially formulated waterproof coating to ensure maximumresistance to moisture penetration, whilst allowing for higher levels ofmisuse in handling and care. This coating also provides excellent electricalinsulation, for improved safety. The electrode has a particularly smooth,soft, arc characteristic that welders find very easy to use. It produces asuperb weld finish, with easy slag removal. It also offers easy strike-up, viaa graphite tip and may be used in all positions (except vertical-up). Theelectrode provides for excellent mechanical properties (see separatetechnical data sheet for full details).

The Hammerhead welding process has been specifically developed tooffer an alternative to conventional wet welding, particularly when poorvisibility conditions exist. The process, which uses our specially formulatedCr-Ni-Mo electrode, offers a no-skill option to traditional MMA welding.Furthermore, welding can take place without the need for traditional jointpreparation, eliminating much of the traditional cleaning requirementsassociated with conventional wet welding. It can even work through paintedstructures (see separate technical data sheet for full details of process andelectrode).

The Swordfish arc-cutting electrode offers an alternative to conventionaloxy-fuel/exothermic cutting operations, with major improvements in safetyand convenience provided. There is no requirement for an external O2supply, which offers a considerable advantage for confined and/or otherdangerous conditions. The electrode will cut all ferrous and non-ferrousmaterials and may be used for piercing holes for bolts, the removal of rivets,cutting of chain and other attachments as well as more standard straightline cutting of structures, etc. (see separate technical data sheet for fulldetails). A full technical report, commissioned by Shell UK, is also availablefor this consumable on request.

Underwater Welding & Cutting Products continued

Our underwater welding Stinger (torch) is the only electrode holder you'llever need! Its unique design allows for complete dismantling andreplacement of all wearable parts, on site, without the need for any specialtools or training. The patented design also allows for the adjustment ofwear. It has an overall length of 200mm (8”), a diameter of 39mm (1½”) andweighs less than 400g (13.5oz). It is easy to use with a simple twistmechanism to tighten and release electrodes and is manufactured from atough, hardwearing, fully insulating material that is virtually indestructible,providing maximum protection to the diver. The design allows for anelectrodes choice ranging from 2.5mm (3/32”) to 5.0mm (3/16”) and isavailable with or without a whip lead and DINSE plug. All parts are availableseparately.

The Scorpion Blue is our exothermic/oxy-fuel cutting lance. Typical usesinclude cutting structures, pipelines, removing jetty and pier legs orfoundations, cutting through concrete caissons, vessels, propellers, justabout anything! The lance will cut through carbon steels, cast irons,stainless steels, non-ferrous metals, concrete, rock and rope, wood andmarine growth (this product requires the supply of oxygen).

Our Piranha 400 amp welding safety isolation switches allow for safeisolation of welding current and voltage. The units are fitted with DINSEstyle quick release cable connectors, contain a large 4 pole push/pull switchand Amp and Volt meters (excludes the Junior model). Units are availableas a portable utility-case or steel enclosures. The utility-case model ishoused in a tough, waterproof, lightweight portable case. The mountedunits are housed in an enamelled steel enclosure. Each unit meets CEdirectives for current carrying equipment as well as Underwriter Laboratory(UL) approvals. For underwater cutting operations we recommend thePiranha Junior, which is fitted with an indicator lamp, rather than amp andvolt meters and this may be used as a portable or fixed mounted unit.

Underwater Welding & Cutting Products continued

Our fully Waterproof Auto-Darkening Welding Lens is another first andis the only waterproof welding filter available. The filter fits into a standardKM welding lens assembly and provides a very convenient welding or cuttingaccessory, allowing the diver to see at all times, making for easy andaccurate strike-up and re-striking. This allows for a significant improvementin weld quality and welder performance. It also makes for a great trainingaid. The filter is powered by the arc, no batteries, knobs or switchesnecessary and it is supplied with a 1 year no quibble guarantee. The filteris preset to operate at approximately #9 shade, as this will typically covermost underwater welding and cutting operations, with a background filterstrength equivalent of #3 shade.
